Answer:
the explanations is down here,
Explanation:
Information
Data reaches a more complex level and becomes information by integrating them to a context. Information provides expertise about facts or persons. Example of information: The information about a date of birth still has very little value when it is unknown to which person it belongs. By adding more information like the name, the linked information creates knowledge about a person.
Knowledge
Knowledge thus describes the collected information that is available about a particular fact or a person. The knowledge of this situation makes it possible to make informed decisions and solve problems. Thus, knowledge influences the thinking and actions of people. Machines can also make decisions based on new knowledge generated by information. In order to gain knowledge, it is necessary to process information.
Answer:
There are multiple critical paths
Explanation:
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
The essential technique for using CPM is to construct a model of the project that includes the following:
- A list of all activities required to complete the project (typically categorized within a work breakdown structure),
- The time (duration) that each activity will take to complete,
- The dependencies between the activities and,
- Logical end points such as milestones or deliverable items.
Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).
considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
